test: add contract verification for php-devops wishlist

18 tests verify the full workspace contract is implemented:
- repos.yaml: loads, required fields, valid types, deps exist,
  topological order, foundations, defaults, meta clone rules, domains
- workspace.yaml: loads, active package in registry
- .core/ folder: exists, has spec doc
- Scripts: setup.sh exists+executable, install scripts exist
- Plugins: marketplace.json exists, all plugins have manifests

Enables archival of core/php-devops and core/go-agent.
